FAQs on GATE Questions with solutions: Turbine Video Lecture - Topper Handwritten Notes & Videos for GATE ME - Mechanical Engineering

1. What is a turbine and how does it work?
Ans. A turbine is a machine that converts the energy of a moving fluid (liquid or gas) into mechanical energy. It typically consists of a rotor with blades that are driven by the fluid flow, causing the rotor to rotate and generate power.
2. What are the different types of turbines used in power generation?
Ans. There are several types of turbines used in power generation, including steam turbines, gas turbines, and hydroelectric turbines. Steam turbines use high-pressure steam to generate power, gas turbines burn fuel to produce hot gases for power generation, and hydroelectric turbines use the force of flowing water to generate electricity.
3. What are the main components of a turbine?
Ans. The main components of a turbine include the rotor, blades, casing, nozzle, and shaft. The rotor is the rotating part of the turbine, the blades are attached to the rotor and extract energy from the fluid flow, the casing surrounds the rotor and directs the fluid flow, the nozzle controls the flow of fluid into the turbine, and the shaft connects the rotor to the generator.
4. What is the efficiency of a turbine?
Ans. The efficiency of a turbine is a measure of how effectively it converts the energy of the fluid into mechanical energy. It is usually expressed as a percentage and is calculated by dividing the actual power output of the turbine by the theoretical maximum power output. Higher efficiency means that more of the input energy is converted into useful output power.
5. What are the advantages of using turbines for power generation?
Ans. Using turbines for power generation offers several advantages. They can be used with a variety of fuel sources, such as coal, natural gas, or renewable sources like wind and water. Turbines are also highly efficient and can generate a large amount of power. Additionally, they can be designed to be compact and have a long operating life, making them suitable for various power generation applications.
